This article describes the new System Management Services (SMS) 1.4 software
features that enhance Sun Fire 15K/12K system availability. This document is
useful for support personnel who have a basic knowledge of the Sun Fire 15K/12K
systems.

In a mission critical environment, high availability is achieved by system
resiliency, appropriate configuration, serviceability, and efficient and
automated restoration processes. The SMS 1.4 software enhancements address all
of these elements and increase availability, serviceability, and diagnosability
of Sun Fire 15K/12K systems.

The SMS software can detect domain hangs/stops, then recover from such
situations by resetting and rebooting the domain. The power-on self-test (POST)
runs at increasing diagnostic levels when the domain panics repeatedly. POST
allows the system to identify and isolate persistent hardware faults.

Standardized messages, component health status, and automatic diagnosis are
powerful features for users and service providers. When combined with dynamic
reconfiguration (DR), automatic diagnosis on Sun Fire 15K/12K systems greatly
increases availability and decreases the scheduled downtime for maintenance.

Requirements

To take advantage of the Sun Fire 15K/12K system's availability
enhancements in the SMS 1.4 software, your system must have Solaris Operating
Environment (Solaris OE) version 8 (2/02) or version 9 (12/03) running on Sun
Fire 15K/12K system controllers (SCs) and domains.

Additionally, you must install the following patches:

If using Solaris 8 OE (2/02), patches 115829-01, 115831-01, and 108528-27
or newer.
